  • Coupling drugs (e.g., antitumoral agents, antisense drugs) to natural or synthetic polymers.
  • Utilizing acid-labile bonds or polypeptide spacers for lysosomotropic targeting.
  • Developing specific bioconjugation procedures with high specificity and mild reaction conditions.

Main Results:

  • Polymer conjugation increases drug blood permanence and reduces kidney ultrafiltration.
  • Enhanced permeability and retention (EPR) effect enables efficient tumor targeting.
  • Successful conjugation of peptides, proteins, and oligonucleotides with improved stability and efficacy.

Conclusions:

  • Polymer conjugation offers significant advantages for delivering various therapeutic agents.
  • Bioconjugation chemistry provides tailored solutions for complex drug delivery challenges.
  • Advanced polymer-drug conjugates are in development for enhanced therapeutic outcomes.
